INSERTABLE ELECTRONIC PRESSURE RECORDER Russian patent published in 2023 - IPC G01L5/162 

FIELD: military technology.

SUBSTANCE: plug-in electronic pressure recorder contains a housing with a piezo pressure sensor placed inside it, an electronic signal conversion/registration module and a power source. A delay line is included in the electrical circuit between the piezo pressure sensor and the electronic module, and the power source is made based on a piezoelectric impact energy generator with a voltage converter, which creates the necessary initial energy to power the recorder in the preliminary period of the shot, and the threshold sensitivity of the piezocrystal used in it to the mechanical load is higher sensitivity of the piezocrystal pressure sensor.

EFFECT: measuring equipment designed to test artillery systems, their components, research gunpowder and ammunition.
